Example:
Calcium sulfate reacts with water to form gypsum.
CaSO₄ + 2H₂O → Gypsum
Another example is the formation of Limonite.
Fe₂O₃ + 3H₂O → Fe₂O₃·3H₂O
Limonite usually shows a yellowish color and is common in lateritic soils.

2. Hydrolysis
Hydrolysis is one of the most important processes of chemical weathering in soil formation.
In this process, water molecules split into hydrogen and hydroxyl ions.
H₂O → H⁺ + OH⁻
The hydrogen ions react with minerals, causing chemical changes and f
